Description
Opfindelsen angår automatisk rensende drænsystem med roterende fleksibel spiralsnegl. Opfindelsen kan anvendes på to takts motorer af krydshoved typen. Opfindelsen er specielt velegnet til anvendelse i de drænsystemer og rør der dræner motorernes stempelstangspakdåser (på engelsk benævnt: Piston rod stuffing box”) og ligeledes skylleluft bælter. (på engelsk benævnt: Scavenge air space eller piston underside space ). Opfindelsen er endvidere velegnet til anvendelse i de drænsystemer der dræner fra motorernes skylleluftbeholder (på engelsk benævnt scavenge air receiver)The invention relates to automatic cleaning drainage system with rotating flexible spiral auger. The invention can be applied to two-stroke cross-head type motors. The invention is particularly suitable for use in the drainage systems and pipes which drain the piston rod packing boxes of the engines (also known as Piston rod stuffing box ”) and also purge air belts. (in English: Scavenge air space or piston underside space). The invention is furthermore suitable for use in the drainage systems that drain from the engine's flushing air tank (scavenge air receiver)
Opfindelsen kan anvendes både som eftermontering på eksisterende motorer og anlæg, såvel som til montage på nye motorer og anlæg.The invention can be used both as retrofitting to existing motors and systems, as well as for mounting on new motors and systems.
Opfindelsen kan anvendes både på tryksatte og på ikke tryksatte (åbne) dræn og rørsystemer.The invention can be applied to both pressurized and non-pressurized (open) sinks and piping systems.
Fig. 1 og Fig. 2 viser en udførselsform af drivenheden (prototype) Den viste udførselsform er beregnet for tryksatte drænsystemer (dræn fra motorens skylleluftbælter og beholdere) Bemærk at Fig. 1 viser en stump snegl monteret i et op-savet demonstrationsrør (fig1-b) Den viste udførselsform er udført med traditionel akseltætning (fig1-c / fig2-a) Dennes funktion er at tætne mod det i røret forekommende tryk (skyllelufttryk). Akselen (fig 2-b) overfører den langsomme roterende bevægelse fra gearmotor til spiralsnegl. Huset (fig2-c) fungerer både som udførslens fondament og som rørets ende flange. Lejehuset (fig2-d) optager akslens aksiale og radiale kræfter via et kugleleje. Gearmotoren (fig2-e) frembringer akslens/sneglens rotation. Gearmotorens roterende kraft overføres gennem en springsplit, monteret gennem hullerne (fig2-f+g) Springsplittens formål er at sikre snegl og gearmotor mod ødelæggende overbelastning. Glidelejets(fig2-h) funktion er dels at optage akslens (fig2-b) radiale kræfter, dels, at komprimere den traditionelle akseltætning (fig2-a) Den komprimerende virkning opnås ved at spænde boltene (fig2-i) således at Glidelejet (fig2-h) trækkes i retning mod huset (fig2-c) herved opnås en tættende virkning mellem den roterende aksel (fig2-b) og det stationære hus (fig2-c) Spiralsneglen (fig2-k) fastspændes på akslen (fig2-b) vha. pinolskrue (fig2-J) i en fordybning i akslen. Beskyttelsesskærmen (fig2-L) monteres på huset (fig2-c) således at den beskytter mod adgang til den roterende aksel (fig2-b) Den induktive sensor (fig2-m) overvåger akslens ønskede rotation.FIG. 1 and FIG. 2 shows an embodiment of the drive unit (prototype) The embodiment shown is intended for pressurized drainage systems (drainage from the engine rinsing belts and containers) Note that Figs. 1 shows a blunt auger mounted in a raised demonstration tube (fig1-b). The embodiment shown is made with traditional shaft seal (fig1-c / fig2-a). Its function is to seal against the pressure present in the tube (rinsing air pressure). The shaft (Fig. 2-b) transmits the slow rotating motion from gear motor to spiral auger. The housing (fig2-c) serves both as the foundation of the export and as the end of the pipe flange. The bearing housing (Figs. 2-d) absorbs the axial and radial forces of the shaft via a ball bearing. The gear motor (Fig. 2-e) produces the rotation of the shaft / auger. The rotary power of the gear motor is transmitted through a spring split, mounted through the holes (fig2-f + g) The purpose of the spring split is to secure the auger and gear motor against destructive overload. The function of the sliding bearing (fig2-h) is partly to absorb the radial forces of the shaft (fig2-b) and partly to compress the traditional shaft seal (fig2-a). The compressive effect is obtained by tightening the bolts (fig2-i) so that the sliding bearing (fig2 -h) is pulled towards the housing (Fig2-c) thereby obtaining a sealing effect between the rotating shaft (Fig2-b) and the stationary housing (Fig2-c). using a pin screw (Fig2-J) in a recess in the shaft. The protective shield (fig2-L) is mounted on the housing (fig2-c) so that it protects against access to the rotating shaft (fig2-b) The inductive sensor (fig2-m) monitors the desired rotation of the shaft.

-2Fig. 3 og Fig. 4 viser en udførselsform af drivenheden (prototype) Den viste udførselsform er beregnet for trykløse (åbne)drænsystemer (dræn fra motorens stempelstangspakdåser) Den viste udførselsform er udført med beholder/bakke for udfældning og opsamling af fast stof. Gearmotoren (fig3-a) er monteret med bolte på drivenhedens kasse(fig3-b) Spiralsneglen(fig3--2Fig. 3 and FIG. 4 shows an embodiment of the drive unit (prototype) The embodiment shown is intended for pressure-free (open) drainage systems (drainage from the engine's piston rod packing boxes). The embodiment shown is made with container / tray for precipitation and solid collection. The gear motor (Fig3-a) is mounted with bolts on the drive unit box (Fig3-b).
c) er monteren direkte på gearmotorens aksel. Gearmotoren overfører sin drejende bevægelse gennem springsplit(fig4-a). Den induktive sensor(fig4-b) overvåger sneglens rotation. Spiralsneglen trækker fast/trægt flydende stof ind gennem røret (fig4-c) En blanding af letflydende olie og fast/trægt flydende stof falder fra røret(fig4-c) ned i udfældnings beholderen(fig4-d) Udfældningsbeholderen vil efterhånden flyde over, hvorved hovedsageligt olie vil forlade drivenheden gennem afgangsrør(fig3-d) Det faste/trægt flydende stof vil udfælde/bundfælde i udfældningsbeholderen(fig4-d) Når udfældningsbeholderen skønnes fuld, kan denne tømmes manuelt ved at løfte den ud af drivenhedens kasse(fig3-b) Låget(fig3e) holdes lukket af håndskruer(fig3-f) under normal drift. Gasstemplerne(fig4-e) holder låget i åben position under arbejde i drivenhedens kasse. Sikkerhedskontakten(fig3-g) forhindre start af gearmotoren(fig3-a) ved åbning af låget(fig3-e)c) is mounted directly on the shaft of the gear motor. The gear motor transmits its rotary motion through the spring split (Fig4-a). The inductive sensor (fig4-b) monitors the rotation of the auger. The spiral screw enters solid / sluggish liquid through the tube (fig4-c) A mixture of light liquid oil and solid / sluggish liquid drops from the tube (fig4-c) into the precipitation vessel (fig4-d) The precipitating vessel will eventually overflow whereby mainly oil will leave the drive unit through discharge pipes (fig3-d) The solid / sluggish liquid will precipitate / settle in the precipitator (fig4-d) When the precipitator is full, it can be emptied manually by lifting it out of the drive box (fig3-b) ) The lid (fig3e) is kept closed by hand screws (fig3-f) during normal operation. The gas pistons (Fig. 4-e) hold the lid in the open position while working in the drive box. The safety switch (fig3-g) prevents starting of the gear motor (fig3-a) when opening the lid (fig3-e)
Det er kendes fra to takts motorer af krydshoved typen, at dræn rør helt eller delvis tilstopper under drift(fig6) Dette fænomen fremkommer, som følge af mediets sammensætning. Mediet består af smøreolie blandet med faste partikler i form af u-forbrændte partikler (slam) Disse faste eller trægt flydende bestanddele har tendens til at udfælde/bundfælde og ophobe sig på rørets inderside(bund). Der opbygges herved relativt hurtigt, lag på lag, en helt eller delvis tilstoppelse af røret under motorens drift. Det opbyggede materiale i røret har nærmest konsistens som hårdt stampet jord. Fænomenet opstår fordi den strømmende del af mediet (olien) flyder gennem røret, uden at være i stand til at holde de faste/trægt flydende bestanddele i tilstrækkelig bevægelse. Der kendes eksempler hvor sådanne rørsystemer tilstoppes efter kun 3 ugers drift siden sidste rengøring. Problemet løses i dag hovedsageligt ved manuelt, at adskille rørsystemer og manuelt rense dem ved hjælp af jernstængerrensebånd og andre kendte værktøjer til rensning af rør. Dette medfører imidlertid relativt stort forbrug af arbejdstimer.It is known from two-stroke engines of the crosshead type that drain pipes completely or partially clog during operation (Fig6). This phenomenon arises due to the composition of the medium. The medium consists of lubricating oil mixed with solid particles in the form of uncombusted particles (sludge). These solid or sluggish liquid components tend to precipitate / settle and accumulate on the inside (bottom) of the pipe. This builds up relatively quickly, layer by layer, completely or partially clogging the pipe during engine operation. The built-up material in the pipe has almost the same consistency as hard stamped soil. The phenomenon occurs because the flowing part of the medium (the oil) flows through the tube, without being able to keep the solid / sluggish liquid components in sufficient motion. There are known examples where such pipe systems are clogged after only 3 weeks of operation since the last cleaning. Today, the problem is solved mainly by manually separating pipe systems and manually cleaning them by means of iron bar cleaning tapes and other known pipe cleaning tools. However, this results in relatively high consumption of working hours.

-3Der kendes eksempler på forbrug af over 1000 arbejdstimer på manuel rensning af disse rør årligt. Derudover er arbejdet til scene for de involverede, da det ofte foregår i ubekvemme stillinger og ofte medfører brug af giftige og potentielt sundhedsskadelige kemikalier og eller diesel olie.-3There are known examples of consumption of over 1000 working hours on manual cleaning of these pipes annually. In addition, the work is the scene for those involved, as it often takes place in inconvenient positions and often involves the use of toxic and potentially harmful chemicals and or diesel oil.
Rørenes renhed er vigtig for motorens funktion. Hel eller delvis tilstoppelse af nævnte rør vil kunne medføre væsentlige driftsmæssige og sikkerhedsmæssige problemer i forbindelse med motorens drift.The purity of the pipes is important for the operation of the engine. Full or partial clogging of said pipe may cause significant operational and safety problems in connection with engine operation.
Opfindelsens formål er, at forebygge ophobning/ helt eller delvis tilstoppelse af drænrør under motorens fortsatte drift, vha. tilpasset rotation af fleksibel spiralsnegl. Opfindelsen vil kunne medføre problemfri drift af disse to takts motorer og vil betyde en drastisk besparelse i mandetimer til manuel rengøring. Opfindelsen vil desuden kunne medføre en væsentlig besparelse i forhold til forbrug af rengøringskemikalier og diesel olie, som forbruges i forbindelse med manuel rengøring af rør.The object of the invention is to prevent accumulation / complete or partial clogging of drainage pipes during continued operation of the engine, by means of adapted rotation of flexible spiral auger. The invention will lead to trouble free operation of these two stroke engines and will drastically save man hours for manual cleaning. In addition, the invention could significantly save on the consumption of cleaning chemicals and diesel oil consumed in connection with manual pipe cleaning.
Den roterende fleksible spiralsnegl kendes fra flexsnegle der f.eks. bruges til transport af foder og granulater i f.eks. landbruget. Ved disse anvendelser er sneglen kendetegnet ved en forholdsvis hurtig rotation og den primære funktion af sneglen er transport (snegleløb) af tørt foder eller granulat gennem et rør.The rotating flexible spiral auger is known from flex augers which e.g. used for transporting feed and granules in e.g. agriculture. In these applications, the auger is characterized by a relatively rapid rotation and the primary function of the auger is the transport (auger run) of dry feed or granules through a tube.
Den roterende fleksible spiralsnegl kendetegnes endvidere ved at være fleksibel, således at den kan følge og fungere i rørets eventuelle bløde bøjninger.The rotating flexible spiral auger is further characterized by being flexible so that it can follow and function in any soft bends of the tube.
Ved det automatisk rensende drænsystem med roterende fleksibel spiralsnegl, er sneglens primære funktion at forhindre aflejring af fast stof (slam). Dette opnås ved en forholdsvis langsom rotation, der frembringer en skrabende virkning på rørets inderside. Den primære medietransport gennem røret forgår ved strømning gennem spiralsneglens hule diameter, samt langs det mellemrum der fremkommer mellem spiralsneglens yderdiameter og rørets inderdiameter.(fig 5)In the automatic cleaning drainage system with rotating flexible spiral auger, the primary function of the auger is to prevent the deposition of solids (sludge). This is achieved by a relatively slow rotation which produces a scraping effect on the inside of the tube. The primary medium transport through the tube is effected by flowing through the hollow diameter of the coil, as well as along the gap between the outer diameter of the coil and the inner diameter of the tube. (Fig. 5)

-4Omtalte strømning fremkommer ved gravitation som følge af rørets hældning eller som følge af trykforskel mellem rørets indløb og udløb. Der forekommer ligeledes systemer hvor strømning fremkommer som følge af en kombination af gravitation og trykforskel.-4Current flow occurs by gravity due to the slope of the tube or due to pressure difference between the inlet and outlet of the tube. There are also systems where flow occurs as a result of a combination of gravity and pressure difference.
Der kendes forskellige roterende rør og afløbsrensere. Disse er kendetegnet ved at skubbe et wire lignende rensebånd ind gennem en åbning i røret. Disse er normalt håndholdte og kræver at der frembringes adgang til en åbning i røret. Disse rør/afløbsrensere anvendes typisk når et rør er helt eller delvist tilstoppet. Formålet med disse er at stikke hul i en evt. tilstopning (prop) i røret. Disse anordninger er ikke beregnet til fasmontering og kontinuerlig præventiv drift.Various rotary pipes and drain cleaners are known. These are characterized by pushing a wire-like cleaning belt through an opening in the pipe. These are usually handheld and require access to an opening in the tube. These pipe / drain cleaners are typically used when a pipe is completely or partially clogged. The purpose of these is to punch in a possible. clogging (plug) in the pipe. These devices are not intended for phase mounting and continuous preventive operation.
Det automatisk rensende drænsystem med roterende fleksibel spiralsnegl kendetegnes ved at være fastmonteret i rørsystemet. Spiralsneglens omdrejningshastighed afpasses så der opretholdes et relativt rent rør ved, at forhindre udfældning og opbygning af fast og/eller trægt flydende materiale. Sneglens omdrejningshastighed afpasses tilpas langsom til at undgå unødig friktion mellem snegl og rør væg. Herved undgås unødig slid samt temperatur stigning på roterende snegl. Spiralsneglens roterende bevægelse kan være både konstant omdrejningshastighed, såvel som varierende hastighed. Opfindelsen kan også udføres med intermitterende (start/stop) roterende bevægelse.The automatic cleaning drainage system with rotating flexible spiral auger is characterized by being fixed in the pipe system. The speed of the spiral screw is adjusted so that a relatively clean tube is maintained by preventing the deposition and build-up of solid and / or sluggish liquid material. The speed of the auger is adjusted slowly to avoid unnecessary friction between the auger and pipe wall. This avoids unnecessary wear and temperature rise on the rotary auger. The rotary motion of the coil can be both constant speed, as well as varying speed. The invention can also be carried out with intermittent (start / stop) rotary motion.
Opfindelsen kendetegnes endvidere ved at have en drivenhed monteret i rørets ene ende. Spiralsneglens skrabende/rensende bevægelse kan foregå med bevægelsesretning væk fra drivenhed - såvel som bevægelsesretning hen mod drivenhed. Drivenheden frembringer en roterende bevægelse af spiralsneglen. Drivenhedens roterende bevægelse kan udføres vha.: elektrisk motor/aktuator, hydraulisk motor/aktuator, pneumatisk motor/aktuator, mekanisk roterende påvirkning eller manuel (håndkraft)The invention is further characterized by having a drive unit mounted at one end of the pipe. The scraping / cleaning motion of the spiral screw can take place with direction of movement away from the drive unit - as well as direction of movement towards the drive unit. The drive unit produces a rotary movement of the helical screw. The rotary movement of the drive unit can be carried out using: electric motor / actuator, hydraulic motor / actuator, pneumatic motor / actuator, mechanical rotary actuation or manual (manual)
